Jerome : (Verse 6) So that they may know, from the rising of the sun, and from the west, that there is no one besides me ((Previously it was added: God)). I am the Lord, and there is no other. And I have done these things so that from the East and the West the whole world may recognize that there is no other God besides me. I am the Lord, and there is no other. For the Father is in the Son, and the Son is in the Father. He who speaks in the Gospel: I and the Father are one (John 10:30). And it is written in the book of Ezra that Cyrus wrote to all nations that there is no God except the God of Israel. Or it is to be understood in this way, that the release of captives and the mercy of God towards his people has made God known to all nations. — Commentary on Isaiah John Chrysostom : The prophets were not denying the Son (God forbid!), but they wished to cure the Jews of their weakness and, meanwhile, to persuade them to give up their belief in the many gods that did not exist. — AGAINST THE ANOMOEANS, HOMILY 5:23 Tertullian : And inasmuch as this Son is undivided and inseparable from the Father, so is he to be reckoned as being in the Father, even when he is not named.

In short, he would have made his Son actually another, after excepting him from others. — AGAINST PRAXEAS 18
